No, you got the right version. The person who created knoppix is German. There is a way to get it to load in english, but without the system in front of me I can't tell you how to do it. It should be on the load page when you start it. You can try
www.knoppix.net for help. I just wanted to post to let you know that you have the right version. It is a great system, one of the best of the linux flavors in my opinion. Good luck with it.
